To all whom it may concern.'

Be it known that I, THnori-rin MARTIN, a citizen of France, and aresident of Newark, county of Essex, vand State of N ew .lersey, haveinvented certain new and useful improvements inl Skylights, of which thefollowing is a specification.

rlhis invention relates toan improved skylight of the kind that can beopenedto permit a minimum of ventilation, or that can be opened toprovide a maximum of ventilation, the top of the skylight not beingnecessarily opened by reason of the skylight being constructed ofsections that are movable vertically and are connected together so thatthey move relative to one another, but such movement is limited. Suchconnection permits of the partial or complete opening of the' sections,according to the amount of movement imparted to the top section, sinceas this is raised to the limit 'ofV its connection with the next lowersection, it raises that next lower section and the next and the next,and so on down until all the sections have been extended to their openpositions. I

The invention is further designed to provide a skylight of this kindwhich, when open, prevents the entrance of Vsnow or water, even with ahigh wind, since the adjacent sections are constructed so that theyoverlap and are provided with deiiecting flanges to prevent the entranceof rain or snow. v

Another object of the invention is to provide a skylight in which theinitial opening is made easy, since the parts are successively raised,and when the opening movement of the skylight is initiated only the topsection needs to be raised and the skylight can be opened with ease,since the weight increases gradually and only after the opening movementis under way.

The invention is illustrated in the accoman' ino' drawin in which Fi ure1 is a .Y es ga side view of one type of skylight of my improvedconstruction in closed position, with the two top sections broken awayto more clearly illustrate the construction thereof.

ll ig. 2 is a side view showing the skylight illustrated in Fig. 1, butin open position. Fig. 3 is al front view of the skylight shown in Fig.1, and Fig. a is a side elevation, on a reduced scale, showing a modiedform of construction.

The skylight is formed of sections, the

bottom or base section 110 being placedon the roof of a building or onany other structure that is to be ventilated, and acts a support for theintermediate sections 11 and the top section 12. The intermediatesections are of any desired number, and each section is fastened to itsnext adjacent section by means of a short chain 13, being secured at anydesired point in the structure, but preferably connecting the sectionsat the corners.

In the form shown in Figs. 1, 2 and 3 the sections,'except the bottomsection, are pivotally secured on a standard 14 by the rods or bolts 15,so that they can be swung on the pivots provided by the rods 15 andlifted into open position. The chains 13 orf :inv other similar elementsact to limit the move.'- ment of one section relative to the sectionnext below it, so that when the top section is raised it is moved untilthe chain that connects it with the next lowersection is taut, and thensaid next lower section is raised, and so on down until the skylight hasall its sections, except the bottom or base section, open.

The upward movement of the sections is limited usually `by fastening thebottomv end of the chains 13 to the base section or suitable fixedsupport, as shown at 16, so that when the last movable section hasreached its limit of movement, the chain is taut and no further movementis permitted.

In the construction shown, the top section is-connected by an arm 17 toa lever 1S pivoted at 19, which is swung by. suitable means, such as arope or cable 20, which can be suitably secured to hold the skylight inits adjusted positions.

I prefer to make the skylight with the top section adapted to admitlight, in the' form shown `this being accomplished by making the topplate of glass, as at 21, and a shelf 22 extends around the inside ofthe top section to catch any waters of condensation which accumulate inthe top of the skylight, such waters of condensation being permitted toflow out through the opening 23.011 the back edge of the vertical flange24C of the top section.

In order to improve the appearance of the skylight, and also to make itadapted for preventing the entrance of snow and water when the skylightis open, I provide the sections with the inwardly and upwardlyprojecting marginal flanges 25, the intermediate sections and the basesection having side flanges 25 merging into a vertical flange 26,

and an outwardly and downwardly project-V mg flange 27. lt will thus beseen thatany moisture being driven into the separated sections, if it isforced by a high wind up the flange 25, is prevented from entering byreason of the flange' 26 and the outwardly projecting dange 2..

l also prefer to use said vertical flanges as the elements torwhich theends of the short lengths of chain are fastened, this be ing shown inFigs. l and 2. With the type of skylight shown in Figs. l, 2 and 3, oneend of each section is pivotally secured to a support. rlhe inwardlyturned flanges 25 are reduced in height toward the pivot, this beingshown in dotted outlineV inthe two lower sections Vof Fig. 2, the rearparts `25L of the flanges 25 being shorter than the forward parts 25",butthe whole structure nests together when the sections are lowered `tofit tightly as in Fig. l.

ln Fig. e lshow a modified form of skylight in which the sections thatare movable are not pivoted, but all rise vertically, the movablesections being secured together by limiting connecting means as abovedescribed, these, however, not being illustrated in Fig. a. 'In thisconstruction the upright rods 28, preferably one on each corner, arefastened to the levers 29, which are pivoted intermediate of their ends,as at 30, and have the slotted ends 3l through which the bar 32 passes,the bar 32 being fastened to the Vrope or cable 33 so that as the rope33 is raised or lowered, the skylight isopened or shut. Y 1

lt will be evident that minor changes may be made in the details of theskylight with- Lacasse l. A skylight comprising a base having` standardsat one end, sections between the standards and hinged thereto,each-section having a right-angled edge with upwardly and inwardlyprojecting flanges thereon,the lastmentioned flanges being tapered sothat they are lowest adjacent the hinge, a top section with its inwardlyand upwardly extending flange of the same height all around, a top tosaid top section, means for raising the top section, and flexibleconnections between all the sections so that theyare successivelyraised, the vend of the lconnection being secured to the base tolimitthe movement of the sections.

2. A skylight comprisinga basefhaving standards at one end, sectionsbetween the standards and 'hingedtheretm each section having varight-angled edge `with upwardly and inwardly projecting flangesthereon, the last mentioned flanges being tapered yso that they arelowest adjacent the hinge, a top section with its inwardly and upwardlyextending flange of thesarne height allaround,.a vertical flange, a topon said top section, a shelfon the inside of the vertical flange, anopening on the hinged end of the top section topermit water on the shelfto -be runoff, and flexible connections between allthe sections so thatthey are successively raised, the

end of the connection beingsecured to the g base to limit the movementof the sections.
